There isn't actually a rhythm guitar on this track but if there were I think it would go 
something like this.
You could also try tuning down a step to Eb and transposing accordingly giving you A 
instead of G#, D instead of C#, E instead of D# etc
making it all open chords which sounds ok all be it not very ramones (but then nor is a 
string section).
